Env: Ubuntu 9.10 running chef 0.8.12
Problem: need to run multiple instances of memcached on one host, but seem to be doing something all wrong.
for the recipe below I have to create a template for each runit instance, also in the define the “#{params[:name]}” is not passed along.
joshua-millers-macbook-pro:site-cookbooks jmiller$ ls -l memcached/templates/default/sv-memcached-11212-*
-rw-r–r-- 1 jmiller staff 33 May 17 23:58 memcached/templates/default/sv-memcached-11212-log-run.erb
-rw-r–r-- 1 jmiller staff 133 May 17 23:55 memcached/templates/default/sv-memcached-11212-run.erb

So I can hack around all this and get a fully working instance but to do that I had to do two defines with hard coded settings, and template for each instance … kind of defeats the point of using any variables.
Question is am I missing something major, is there a better way, or am I just hitting a limit of the runit_service
Thank you,
Joshua
